There was a similar question in forum : [SOLVED] J-Link Flash Loader: erase and program maximum times in FlashDevice But when it comes to prgram SEGGER_FL_Program() takes a param -> Number of bytes to be programmed (always a multiple of FlashDevice.PageSize) Does it mean we have to program a page and return ? ( which i doubt), so how does the timeout for program work when we loop thru several pages to cover the NumBytes to program ?

Also attaching the Jflash testdata vs "Read data" mismatch

Here is my struct struct FlashDevice 0x0101, { "Template flash" }, 1, //0x08000000, //0x00080000, // Flash size == 512 KB 0x90000000, 0x04000000, // Flash size == 64MB 256, // Make sure that SEGGER_FL_Program() is called with a multiple of 4 bytes 0, 0xFF, 200, // Programing timeout (set to 200 ms) 6000, // Erasing a 128 KB sector can take some time... { // Sectorization: { 0x00020000, 0x00000000 }, // 512 * 128 KB { 0xFFFFFFFF, 0xFFFFFFFF } // Indicates the end of the flash sector layout.

DSK Template project was used to build a ELF that satisfies the JFlash utlities requirement (Section,segment etc). The ELF works well in all erasing aspects. Reading works (i have doubts though, read below). Because when i use an other test project (built on different IDE) to crosscheck & comapre the read contents from jflash, i see a difference. based on this i got 2 questions. Any help or thoughts higly appreciated. 1. When we use struct "FlashDevice" ; there is a param TimeoutProg; Ex:"140 pa…

The Driver for the New External Flash has been Unit tested on the SFL project and does all core(mandatory) functions work OK. same ELF generated from this project in kept in path <C:\Users\XXX\AppData\Roaming\SEGGER\JLinkDevices> and Jlink when launched Connects "Successfully" to my newly added Entry in “Target Device” , But when I try to use the Read (target->Manual Programming->Read Back -> selected Sectors) I get this below message: " Timeout while blank checking, RAMCode did not respond in t…
